When someone sends you their location in the chat interface, that can be used while browsing the website, we now also provide you the information about where their IP address shows their location to be.  Obviously if the user is using a proxy the map and IP locations may be different but it gives you the opportunity to be a little more cautious with these users.

You will also notice a small globe next to the users name in the chat window. This will also show their location if you hover over it.
